The longhorn crazy ant (Paratrechina longicornis), also known as the black crazy ant, is a species of small Formicine ant. These ants are commonly called "crazy ants" because instead of following straight lines, they dash around erratically. They have a broad distribution, including much of the tropics and subtropics, and are also found in buildings in more temperate regions, making them one of the most widespread ant species in the world. This species, as well as all others in the ant subfamily Formicinae, cannot sting. However, this species can fire/shoot a formic acid spray from its abdomen when under attack by other insects or attacking other insects. When the longhorn crazy ant (Paratrechina longicornis) bends its abdomen while aiming at an enemy insect, it is typically shooting its hard-to-see acid.
These ants can be touched safely, similar to the ghost ants. The worker longhorn crazy ant is about 2.3 to 3.0 mm (0.09 to 0.12 in) long with a brownish-black head, thorax, petiole, and gaster, often with a faint blue iridescence. The body has a few short, whitish bristles and the antennae and limbs are pale brown. Distinguishing this ant from other members of its... Wikipedia →

Rare
Under 5% of wildlife watchers report a Longhorn Crazy Ant sighting in Belo Horizonte on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 162nd most-seen of the 186 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January–February and October–November

GBIF citizen-science records
It is estimated from how often the Longhorn Crazy Ant is recorded against all the insects logged in Belo Horizonte (5 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
